Cigarette Stuffing Device Slide Stop Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for stuffing prefabricated cigarette tubes are expensive to manufacture and difficult to adapt to different filling space lengths, limiting their versatility and efficiency.
Innovation Solution
A device with a selectively attachable stop that shortens the displacement path of the slide relative to the housing, allowing for easy assembly and disassembly, and an abutment that protrudes into the tobacco chamber by the same length, enabling adaptation to various cigarette tube lengths, including those with extended filters or activated charcoal areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the abutment is designed as an adjustable part with latching positions to adapt to different filling space lengths, then the device can accommodate various cigarette tube lengths, but the device complexity and manufacturing cost increase
Solution Approach 1:
The abutment is divided into a fixed base part and a separate adjustable extension part that can be attached or removed. This segmentation allows the extension part to be positioned at different locations along the slide's displacement path, enabling adaptation to different filling space lengths without requiring complex adjustment mechanisms for the entire abutment structure.
Solution Approach 2:
The adjustable functionality is extracted from the main abutment structure and implemented through a separate extension part that can be independently positioned. This extension part is held in place by adhesive force, eliminating the need for complex latching mechanisms while still providing adaptability to different cigarette tube lengths.
2Adaptability or versatility
If the tobacco support is made displaceable relative to the abutment to automatically adapt to different filling space lengths, then the adaptability improves, but the device complexity and manufacturing cost increase
Solution Approach 1:
The system is segmented into fixed components (housing, slide, spout) and a movable component (tobacco support with abutment extension). The tobacco support is designed to be displaceable along with the slide, and the abutment extension is positioned to engage with the cigarette tube at the appropriate location, providing automatic adaptation without complex control mechanisms.
Solution Approach 2:
The tobacco support automatically positions itself relative to the cigarette tube during the stuffing operation. The displaceable abutment extension engages with the cigarette tube wall, and the system self-adjusts to different filling space lengths through the natural displacement of the slide and tobacco support assembly, eliminating the need for additional adjustment mechanisms.
3Adaptability or versatility
If an insert is provided in the tobacco chamber to adapt the length and form a stop, then the adaptability to different filling space lengths improves, but the manufacturing cost and device complexity increase
Solution Approach 1:
The abutment extension is merged with the tobacco support structure, forming an integrated component that serves both as a structural element and as the adaptive feature. This eliminates the need for separate inserts in the tobacco chamber, reducing the number of parts and simplifying manufacturing while maintaining adaptability to different filling space lengths.
4Adaptability or versatility
If multiple adjustable components are provided to adapt to different cigarette tube configurations, then the versatility improves, but the ease of operation and manufacturing simplicity deteriorate
Solution Approach 1:
The system is segmented into a fixed slide assembly and a displaceable tobacco support with an attachable abutment extension. This segmentation allows the extension to be easily attached or removed based on the cigarette tube configuration, simplifying operation while maintaining versatility.
Solution Approach 2:
The system adapts to different cigarette tube configurations by changing the position of the abutment extension along the slide's displacement path. This parameter change (positioning) provides versatility for different filling space lengths and filter extensions without requiring complex mechanical adjustments, maintaining ease of operation.

AI summary
The invention relates to a device for stuffing prefabricated cigarette tubes, having a housing, a tobacco chamber, a tobacco rest associated with the latter, a movable press bar for shaping the tobacco placed into the tobacco chamber into a line, a counter bearing associated with the tobacco rest for one end of the tobacco line and a slide, which can be displaced relative to the housing in order to fill the tobacco line in the cigarette tube. On the slide a stop (29) is provided, which can optionally be activated or can optionally be attached to the slide, and which shortens the displacement path relative to the housing by a length when in the activated or attached state. The counter bearing is formed in such a manner that the counter bearing projects into the tobacco chamber by the length when the stop is activated or attached.
